Abstract
A system is disclosed for closing a pivoting door thrust reverser pivotally attached to a jet engine cowling including a latch mechanism that is movably connected to the jet engine cowling and movable between a first position in which the latch grips a forward portion of the thrust reverser door when the forward portion of the thrust reverser door is a predetermined distance from the fully closed position and a second position in which the latch mechanism exerts a force on the thrust reverser door to urge the thrust reverser door to the fully closed position. In this manner, a relatively large closing torque is exerted on a forward portion of the thrust reverser door by the movable latch mechanism. Since the force is applied a relatively large distance from the pivot axis of the thrust reverser door, the requisite torque may be generated by actuator having a relatively low force.
